add support for more syntax flexibility about iterrr HOT 2 CLOSED

i don't this is necessary. it adds a lot of complexity over core and it's not very common.
you can do it instead if you wanted

template op(num): untyped = 
   echo num
   num + 1

1..10 >< imap(op it)

from iterrr.

I'm not sure but maybe this would be possible too.

call(echo 1; echo 2) # doesn't work
call((echo 1; echo 2)) # maybe ?!

That would be better than defining a template

UPDATE: (stmt1; stmt2; expr) works

you can do multiline too.

proc parseInput(fname: string): auto =
  fname.lines >!< imap[line](
    line.split(" -> ") >< imap((
      let (_, a, b) = scantuple(it, "$i,$i")
      (a, b)
    ))
  )

echo parseInput "inp.txt"

but seriously, it's a bad style. don't use it

from iterrr.
